(3,4) And they can bind to erythrocytes,simultaneously with immune factors, causing hemagglutination and anemia. (5)Of the 119 known dietary lectins, about half are panhemagglutinins, clumping allblood types. The remainder are blood-type specific.
Two of the four cells will contain one recombinant chromosome. In eukaryotic cells, crossing over can also occur during mitosis. Somatic cells (non-sex cells) undergo mitosis to produce two distinct cells with identical genetic material.
Crossing over results in recombination of genes found on the same chromosome, called linked genes, that would otherwise always be transmitted together. Because the frequency of crossing over between any two linked genes is proportional to the chromosomal distance between them, crossing over frequencies are used to construct genetic, or linkage, maps of genes on chromosomes.
